I created two partitions on my removable Flash drive, but Windows doesn't recognize the second partition.
Both partitions are NTFS and primary partitions.
And this image is in disk management on Windows 7.
and also with EASEUS Partition Master
Have you looked in disk management? Perhaps checked that both have a drive letter assigned to them?
Windows does not support multiple partitions on removable flash drives. The drive must be either non-removable or non-flash.
The Web describes various methods how to make removable flash drives work, but in general case you are better off using a non-flash medium for this (like a USB HDD/USB SSD).
